How do you write -x - y = - 8 into slope intercept form?

Aug 7, 2015

$y = - x + 8$

Explanation:

The slope-intercept form for a linear equation is $y = \textcolor{red}{m} x + \textcolor{b l u e}{b}$, where $\textcolor{red}{m}$ is the slope and $\textcolor{b l u e}{b}$ is the y-intercept.

$- x - y = - 8$

Add $x$ to both sides.

$- y = x - 8$

Multiply both sides times $- 1$.

$y = - x + 8$

$\textcolor{red}{m} = - 1$

$\textcolor{b l u e}{b} = 8$
